CUTTING APPARATUS FOR HARVESTERS.

S1"ECIIEICA'LION formingpart of Letters Patent No. 400,489, dated April2, 1889. Application iiled June 28, 1.888. Serial No. 278,480. (Nomodel.)

.To all whom, it may concern:

Be it known that we, ROBERT JOHNSTON ROBINSON and CYRUs FREEMONTCOLLINS, citizens of the United States, residing at Linneus, in thecounty of Linn and State of Missouri, have invented a new and usefulImprovement in Cutting Apparatus for Harvesters, of which the followingis a specification.

Our invention relates to an improvement in cutting' apparatus forharvesters; and it consists in the peculiar construction and compbination of devices that will be more fully set forth hereinafter, andparticularly pointed out in the claims.

In the drawings, Figure l is atop plan View of a cutting apparatusembodying our improvements. Fig. 2 is an inverted plan view of the same.Fig. 3 is a vertical sectional view taken on'the line x of Fig. l. Fig.4 is a similar view taken on the line y y of Fig. l. Fig. 5 is adetailed perspective view of one of the plates K..

A represents the finger-bar, which is of the usual construction, and Brepresents the iingers, which project from the front side of thefinger-bar, and have the rearward-extending arms C, which are secured tothe under side of the finger-bar by means of bolts D.

The fingers B are of the usual construction, having the open slot-s E,and F represents a cutter-bar, which is arranged over the fingers andbears against the rear edge of a guidebar, H, which guide-bar 'issecured in the front ofthe seat for the cutter-bar by means of bolts H',that bear against the shoulders at the inner end of the fingers. Securedto the said cutter-bar are the usual cutters, I, which are operated inthe slots E of the fingers.

K represents plates, which are arranged on the upper side oftheinger-bar A, and have their front sides bent downward at L andbearing against the front edge of the linger-bar. From the saidverticalportions L, at the lower end thereof, extendforwardly-projecting horizontal arms M, the outer ends of which arecurved upward, as shown, to form toes m', that bear against the lowerfront edge of the guide-bar H, and said arms M are further provided withrectangular openings fm2, and have vertical arms m3 at a suitabledistance from their outer ends. In said arms m3 and in the verticalportion L are journaled anti-friction rollers N, the upper sides ofwhich bear against the lower side of the cutter-bar F, and the lowersides of which are in the openings m2. The plates K have slots O, whichare arranged transversely on the nger-bar and adapt said plates to beadjusted thereon, as shall presently appear.

P represents plates, which are arranged on the finger-bar, and areprovided on their front sides with arms R S. The arms R bear upon theupper side of the cutter-bar and the arms Sare turned upward at rightangles and provided each with a vertical slot, T.

U represents spindles, which are arranged in the slots T and secured tothe bars S by means of clamping-nuts V. On the said spindles arejournaled anti-friction rollers W, which bear upon the upper sides ofthe cutters.

'In the front side of the finger-bar, at suitable distauces apart, arecircular recesses or notches X.

Y represents vertical spindles, which are secured to Iand dependent fromthe plates P at the inner ends of the arms R, and on the lower ends ofsaid spindles are journaled antifricton rollers Z, which bear againstthe rear edge of the cutter-bar.,

The plates P are provided'with parallel slots A', which are arrangedtransversely on the finger-bar, and one of said slots in each plate Pregisters with the slot in the proximate plate K. Clamping -bolts Bextend through the slots in the plates P and K and enter the finger-barand serve to secure the plates'thereon at any desired adjustment.

By means of the slots in the vertical arms S the rollers WV may be adjusted vertically, so as to cause the cutter-bar at all times to bearfirmly on the guide-bar H and the rollers N, and thereby prevent thecutters from inclining upward and impairing the. efficiency of thecutting apparatus. The plates P and K being adjustable transversely onthe iingerbar, the Vrollers Z and N may be caused at all times to bearagainst the rear and under sides of the cutter-bar as the same becomesWorn, so as to prevent the Cutter-bar from working loose.

Having thus described my invention, l claim- 1. The combination, withthe iinger-bar and the fingers secured thereto, of the cutter-bar, theplates P, secured to and adjustable on the linger-bar and having thevertical slotted arms S, the spindles U, adjustable in said slottedarms, the rollers W', journaled on said spin'- dles and bearing on theCutter-bar, the plates K, secured to and adjustable on the finger-barand having the downwardly-bent front sides, L, and the horizontal armsM, extending forward therefrom with the vertical arms m3 near 2o platesP, and the rollers Z, journaled on said spindles and bearing against therear side of the cutter-bar, substantially as described.

2. The combination of the finger-bar, the fingers secured thereto, thecutterbar supported on the lingers, the guide-bar secured on the lingersand bearing against the front side of the cutter-bar, the adjust-ableplates' secured to the linger-bar, and the anti-friction.
